Detailed Description
The invention is further illustrated by the following figures and examples.
The combined cage type sea wave power generation device with the safety structure shown in fig. 1 to 4 comprises a plurality of water collection units, a water collection pipe, a water collection tank, a hydraulic generator and a controller, wherein the plurality of water collection units float on the sea through the combined cage type placement frame, the water collection units are connected with the water collection tank through the water collection pipe, the hydraulic generator is installed in the water collection tank, and an air pump is arranged on the water collection tank; the water collecting unit comprises a frame, a floater, a piston and a water pressing pipe, the floater is arranged in the frame and floats in the sea, an accommodating cavity is formed in the floater, a high-pressure air chamber is arranged in the accommodating cavity, and the high-pressure air chamber is connected with an air pump through a connecting pipe; the floater is provided with a water inlet valve and a first exhaust valve which are used for being connected with the accommodating cavity, the high-pressure gas is provided with a second exhaust valve, and the high-pressure gas chamber is communicated with the accommodating cavity through the second exhaust valve; the air pump, the water inlet valve, the first exhaust valve and the second exhaust valve are all connected with the controller; the water pressing pipe is arranged in the frame, the upper end of the water pressing pipe is connected with the water collecting pipe through a first communicating pipe, and the lower end of the water pressing pipe is connected with the water collecting pipe through a second communicating pipe; the piston is arranged in the pressurized water pipe and is positioned between the first communicating pipe and the second communicating pipe; the first communicating pipe and the second communicating pipe are respectively provided with a first one-way valve and a second one-way valve; a first water inlet is formed in a section of a first communicating pipe between the first one-way valve and the water pressing pipe, a third one-way valve is arranged at the first water inlet, a second water inlet is formed in a section of a second communicating pipe between the second one-way valve and the water pressing pipe, and a third one-way valve is arranged at the second water inlet; a first guide rod and a second guide rod are respectively arranged above and below the piston, a first through hole and a second through hole are respectively arranged on the upper end surface and the lower end surface of the water pressing pipe, the upper end of the first guide rod penetrates through the first through hole, and the lower end of the second guide rod penetrates through the second through hole; the upper end of the first guide rod is connected with the floater through a first cable, and the lower end of the second guide rod is connected with the floater through a second cable.
Specifically, in the actual working process, the floater in each water collecting unit floats on the sea, the lower half part of the floater is immersed in the sea, and the upper half part of the floater is positioned on the sea surface; the floaters fluctuate up and down along with the sea waves, and in the process that the floaters fluctuate up and down, the floaters drive the pistons to move up and down together through the first cable and the second cable; the area of the piston is far smaller than that of the floater, so that a water pressure far higher than that outside the pressurized water pipe is formed on the surface of the piston inside the pressurized water pipe;
when the piston moves upwards along with the flow waves, the first check valve and the fourth check valve are both in an open state, the second check valve and the third check valve are in a closed state, the seawater between the piston and the upper end face of the water pressing pipe is pressed into the first communication pipe along with the gradual rising of the piston, and the seawater flowing into the first communication pipe flows into the water collecting tank through the water collecting pipe; meanwhile, seawater in the sea enters the water pressurizing pipe from the fourth one-way valve and a second communicating pipe between the second one-way valve and the water pressurizing pipe so as to play a role in collecting seawater;
when the piston moves downwards along with sea waves, the first one-way valve and the fourth one-way valve are both in a closed state, the second one-way valve and the third one-way valve are in an open state, the seawater between the piston and the lower end face of the water pressing pipe can be pressed into the second communicating pipe along with the gradual descending of the piston, and then the seawater in the second communicating pipe flows into the water collecting tank through the water collecting pipe; meanwhile, seawater in the ocean enters the pressurized water pipe from the third one-way valve and the second communicating pipe between the first one-way valve and the pressurized water pipe, so that the seawater collecting effect is achieved.
Therefore, when the floater in each water collecting unit fluctuates up and down along with sea waves, the collected seawater is pressed into the water collecting pipe through the first communicating pipe or the second communicating pipe by the piston and then flows into the water collecting tank, the seawater collected by the plurality of water collecting units is simultaneously pressed into the water collecting tank, the air pump provides stable and adjustable air pressure for the water collecting tank, the seawater in the water collecting tank has pressure difference which is relatively higher than the seawater outside the water collecting tank, and therefore the seawater in the water collecting tank can drive the hydraulic generator to generate power. The depth and pressure of the water in the water collecting tank are mainly automatically controlled by the water outlet flow of the hydraulic generator.
The utilization rate of kinetic energy generated by sea waves is fully improved, and the power generation efficiency is ensured. Meanwhile, the combined cage type sea wave power generation device is simple in structure, the whole combined cage type sea wave power generation device can be directly floated on the sea, the combined frame type structure is high in wind and wave resistance, the total power generation amount can be increased by simply increasing the number of the water collecting units, various marine environments are applied, and the installation and maintenance are convenient.
In the above-mentioned working process of generating electricity by collecting water, when large sea waves appear on the sea surface, the sea waves easily flap the power generation device. The water inlet valve and the first exhaust valve are in an open state, and the second exhaust valve is in a closed state, so that the seawater is filled into the accommodating cavity until the accommodating cavity is filled with the seawater. Because the holding cavity is filled with seawater, the buoyancy of the whole power generation device is smaller than the gravity of the whole power generation device, so that the whole power generation device is submerged into the sea, the flapping of the sea waves is avoided, and the power generation device is prevented from being damaged by the sea waves. When the sensor in the suspension detects that the sea waves are reduced, the water inlet valve is closed, the first exhaust valve and the first exhaust valve are opened, and then gas in the high-pressure gas chamber is exhausted, so that after the seawater in the accommodating cavity is completely extruded out of the accommodating cavity, the water inlet valve, the first exhaust valve and the second exhaust valve are completely closed. At the moment, the buoyancy of the whole power generation device is larger than the gravity of the whole power generation device, and the whole power generation device rises to the sea surface again to collect water and generate power again. Meanwhile, the high-pressure air is stored in the high-pressure air chamber in the floater again by utilizing the electric energy of the device and the air compressor, so that the device can repeatedly execute the actions when in need. On the basis of the original structure, the safety structure formed by the accommodating cavity, the high-pressure air chamber, the water inlet valve and the like is additionally arranged, the power generation device is prevented from being damaged by sea waves, and the safety and the working reliability of the whole power generation device are improved.
A first guide wheel is arranged at the upper end of the frame, one end of a first cable is fixedly connected with the upper end of the first guide rod, and the other end of the first cable passes through the first water inlet, bypasses the first guide wheel and is connected with the floater; the lower end of the frame is provided with a second guide wheel, one end of a second cable is fixedly connected with the lower end of the second guide rod, and the other end of the second cable penetrates through the second water inlet and then bypasses the second guide wheel to be connected with the floater. The arrangement of the first guide wheel and the second guide wheel can change the force transmission direction, so that the linkage reliability between the piston and the floater is ensured, and the water collection efficiency is ensured.
The frame is connected with a suspension through a third cable, a sensor is arranged in the suspension, and the sensor is connected with the controller. When the power generation device submerges into the sea, the suspended floating body floats on the sea surface, and the sensor in the suspended floating body monitors the size of sea waves in real time so as to transmit information of the sea waves to the control, and the control controls the opening and closing of the water inlet valve, the first exhaust valve and the second exhaust valve according to the information, so that the power generation device is controlled to sink or rise in time.
The diameter of the float is smaller than the wave width of the sea waves. I.e. the diameter of the float, is determined according to the wave width of the waves in the sea area where the power plant is to be used. The diameter of the floater is smaller than the wave width of sea waves, so that on one hand, the amplitude of the floater is improved, and the energy absorption efficiency of a single floater is improved; on the other hand, large and wide ocean waves are divided into small pieces, and the impact of a single floater on the frame is reduced.
The water collecting tank is provided with a storage battery, and the water inlet valve, the first exhaust valve and the second exhaust valve are all connected with the storage battery. The structure is simple, the installation is convenient, and the working reliability is further ensured.
The placement frame is provided with a paddle, a rudder and a GPS. The arrangement enables the power generation device to have certain cruising capacity.
The upper end of the water collecting tank is provided with an air port, and the air port is connected with an air pump through an air pipe. This simple structure, simple to operate guarantees to have appropriate atmospheric pressure in the header tank to improve water collection efficiency.
The inner wall of the frame is provided with a guide rail, the outer wall of the floater is provided with a sliding pair matched with the guide rail, and the sliding pair is connected with the guide rail. This can ensure the stability and smoothness of the up-and-down movement of the float, thereby ensuring the water collecting efficiency.
The upper end of the water collecting tank is provided with a gas port which is connected with an air pump through an air pipe, and the lower end of the water collecting tank is provided with an overrun relief valve port. This simple structure, simple to operate guarantees to have appropriate atmospheric pressure in the header tank to improve water collection efficiency.
The plurality of water collecting units are distributed in the arrangement frame in a matrix manner. The structure is compact in arrangement, convenient to install and capable of ensuring the stability of the whole structure.
A safe sinking mechanism is arranged in the water collecting tank. The specific structure of the safety sinking mechanism is the same as the sinking structure formed by the high-pressure air chamber in the float and each exhaust valve (i.e. the first exhaust valve, the second exhaust valve, etc.). Namely, the safe sinking mechanism in the water collecting tank also comprises a high-pressure air chamber, the high-pressure air chamber is connected with an air pump, and an exhaust valve is arranged in the high-pressure air chamber. The safety sinking mechanism arranged in the water collecting tank is the same as the internal structure of the floater, and the floating and sinking of the whole power generation device are controlled by adjusting the water amount in the water collecting tank, so that the whole power generation device is protected.
